Dear Student,
◆ Answer -
Probability that the ball drawn has prime number = 4/13
● Explanation -
Total numbers between 5 to 30 are -
Set S = {5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30}
n(S) = 26
Prime numbers between 5 and 30 are -
Set A = {5, 7, 11, 13, 17, 19, 23, 29}
n(A) = 8
So probability that the ball drawn has prime number -
P(A) = n(A)/n(S)
P(A) = 8/26
P(A) = 4/13
So, the probability that the ball drawn has prime number is 4/13.
Thanks dear. Hope this helps..
