Q1. A cricketer faced 40 deliveries in a season and scored a boundary off 9 of them. Based on this record, what is the experimental probability that she scores a boundary off a delivery she faces?
- A.0.775
- B.9/40
- C.0.225
- D.0.2903
Answer: C. 0.225
Experimental probability = favourable trials / total trials = 9/40 = 0.225 (here 9 successes out of 40 attempts).
Q2. A goalkeeper attempted to stop 250 penalty kicks during a tournament and succeeded 90 times. What is the experimental probability that he stops the next penalty he faces?
- A.0.5625
- B.9/25
- C.0.64
- D.0.36
Answer: D. 0.36
Experimental probability = favourable trials / total trials = 90/250 = 0.36 (here 90 successes out of 250 attempts).
Q3. A basketball player took 160 free throws across the league and made 56 of them. What is the experimental probability that her next free throw goes in?
- A.7/20
- B.0.65
- C.0.35
- D.0.5385
Answer: C. 0.35
Experimental probability = favourable trials / total trials = 56/160 = 0.35 (here 56 successes out of 160 attempts).
