Question

Runs scored by $22$ batsmen in a test match are given here:

Runs	$0-9$	$10-19$	$20-29$	$30-39$	$40-49$	$50$ and above
No. of batsman	$2$	$4$	$3$	$5$	$4$	$4$

Find the probability that a batsman selected at random scored runs
above $50$

Answer 1

Total number of batsmen = 22

Number of batsmen scoring runs above 50 = 4

Hence the probability that a batsman selected at random scored runs

above 50 = $\frac{\text{number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{4}{22}=\frac{2}{11}$
