Q. If a clock shows 4:20, what is the angle between the hour and minute hand?
A.
120 degrees
B.
130 degrees
C.
140 degrees
D.
150 degrees
Solution
At 4:20, the hour hand is at 130 degrees (4 hours * 30 degrees + 20 minutes * 0.5 degrees) and the minute hand is at 120 degrees (20 minutes * 6 degrees). The angle between them is |130 - 120| = 10 degrees.
Q. If a clock shows 4:20, what is the angle between the hour and minute hands?
A.
120 degrees
B.
130 degrees
C.
140 degrees
D.
150 degrees
Solution
At 4:20, the hour hand is at 130 degrees (4*30 + 20*0.5) and the minute hand is at 120 degrees (20*6). The angle between them is |130 - 120| = 10 degrees.
Q. If a clock shows 5:00, what is the angle between the hour and minute hand?
A.
150 degrees
B.
180 degrees
C.
120 degrees
D.
90 degrees
Solution
At 5:00, the hour hand is at 150 degrees (5 hours * 30 degrees) and the minute hand is at 0 degrees. The angle between them is |150 - 0| = 150 degrees.
Q. If a clock shows 9:15, what is the angle between the hour and minute hands?
A.
112.5 degrees
B.
90 degrees
C.
135 degrees
D.
75 degrees
Solution
At 9:15, the hour hand is at 97.5 degrees (9*30 + 15*0.5) and the minute hand is at 90 degrees (15*6). The angle between them is |97.5 - 90| = 7.5 degrees.
Q. If a coin is flipped three times, what is the probability of getting exactly two heads?
A.
3/8
B.
1/2
C.
1/4
D.
1/8
Solution
The total outcomes are 2^3 = 8. The combinations for exactly 2 heads are HHT, HTH, THH, which gives us 3 favorable outcomes. So, the probability is 3/8.
