Question

5. Find the probability that a number selected at random from the numbers 1,2,3, ...35 is a; (a) multiple of 4 (b) a prime number.​

Answer 1

Answer:

a={4,8,12,16,20,24,28,32}

n(a)=8

b={2,3,5,7,11,13,17,19,23,29,31}

n(b)=11

Answer 2

Step-by-step explanation:

a) Multiples of 4: 4,8,12,16,20,24,28,32

As we know, P= No. of favourable Outcomes/ Total no. of Outcomes

Therefore, P (Multiple of 4) = 8/35

b) Prime numbers: 2,3,5,7,11,13,17,19,23,29,31

Therefore P (A Prime Number) = 11/35
