Question

a pair of die is thrown.find the probability of getting sum of no. which is a perfect square and divisible by 5

Answer 1

Answer:

Step-by-step explanation:

A pair of die is thrown

∴The sample space is 36

S= {(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6) }

Let A be the event of getting sum of number which is a perfect square

A= {(1,3) (2,2) (3,1) (3,6) (6,3) (5,4) (4,5)}

n (A)=7

p (A)=7÷36

Let B be the event of getting sum of no. divisible by 5

B= { (1,4) (4,1) (2,3) (3,2) (5,5) (6,4) (4,6) }

n (B)=7

p (B)=7÷36
