Question

16) sprots club contain 7 cricketer, 5 footballers , 3 swimmer if
two students pick at random what is the probability that
Both are cricketers​

Answer 1

Step-by-step explanation:

Total people 7+5+3= 15

if first one is cricketer then probability is 7/15

then 1 people lose from total number, 15-1=14

and cricketer is became 7-1=6

if second one is also cricket and then probability is 6/14 or. 3/7

probability of both our cricketers are 7/15 *3/7 or 1/5

Answer 2

Step-by-step explanation:

Sports club contains 7 cricketer, 5 footballers , 3 swimmer,

therefore n(s) =15

Let the probability of Both the cricketers be A.

therefore,

Event A = both are Cricketers

I.e n(A) =7

.

(i). P(A) =n(A)

n(s)

(ii) P(A) =7

15

Ans. The probability that both are cricketers is 7
