Q. In a family with 3 children, what is the probability that at least one of them is a girl?
A.
1/8
B.
1/2
C.
7/8
D.
3/8
Solution
The only scenario where there are no girls is if all three children are boys, which has a probability of (1/2)^3 = 1/8. Therefore, the probability of having at least one girl is 1 - 1/8 = 7/8.
Q. In a football match, a player scored 3 goals in the first half and 2 goals in the second half. What is the ratio of goals scored in the first half to the total goals scored? (2020)
A.
3:5
B.
2:5
C.
1:2
D.
3:2
Solution
Total goals scored = 3 + 2 = 5. The ratio of goals in the first half to total goals is 3:5.
Q. In a football match, a player scores 3 goals in the first half and 2 goals in the second half. What is the ratio of goals scored in the first half to the total goals scored? (2020)
A.
3:5
B.
2:5
C.
1:2
D.
3:2
Solution
Total goals scored = 3 + 2 = 5. The ratio of goals in the first half to total goals is 3:5.
Q. In a genetic experiment, a plant with genotype AaBb is crossed with another plant of genotype Aabb. What is the probability of obtaining an offspring with genotype Aabb?
A.
1/4
B.
1/2
C.
3/4
D.
1/8
Solution
The possible genotypes from the cross AaBb x Aabb are AaBb, Aabb, AABb, and Aabb. The probability of Aabb is 1/2.
Q. In a genetic study, if a trait is controlled by a single gene with two alleles, where one allele is completely dominant over the other, what is the expected genotypic ratio in the offspring of a monohybrid cross?
A.
1:2:1
B.
3:1
C.
1:1
D.
9:3:3:1
Solution
The expected genotypic ratio from a monohybrid cross is 1:2:1.
Q. In a genetic study, if a trait is controlled by a single gene with two alleles, where one allele is completely dominant over the other, what type of inheritance pattern is this?
A.
Codominance
B.
Incomplete dominance
C.
Complete dominance
D.
Polygenic inheritance
Solution
This describes complete dominance, where one allele completely masks the effect of the other.
Q. In a genetic study, if a trait is controlled by a single gene with two alleles, how many different genotypes can be formed from two heterozygous parents?
A.
1
B.
2
C.
3
D.
4
Solution
From two heterozygous parents (Aa x Aa), the possible genotypes are AA, Aa, and aa, resulting in 3 different genotypes.
Q. In a group of 50 people, 30 like tea, 20 like coffee, and 10 like both. What is the probability that a person chosen at random likes either tea or coffee?
A.
1/2
B.
3/5
C.
4/5
D.
1/5
Solution
Using the principle of inclusion-exclusion, P(Tea or Coffee) = P(Tea) + P(Coffee) - P(Both) = (30/50) + (20/50) - (10/50) = 40/50 = 4/5.
Q. In a national election, if 65% of the votes are in favor of a candidate and there are 1,000,000 votes cast, how many votes did the candidate receive?
