Question

10. Cards marked with numbers 5,6,7,..
74 are placed in a bag and mixed
thoroughly. One card is Drawn at random from the bag.
Find the probability that the number on the card is a perfect square​

Answer 1

Answer:

3/35

Step-by-step explanation:

P(E)= no. of favorable cases/total no. of cases

no. of favorable cases = 6 (squares of 3 till 8 ,since closest square to 5 is 9 and closest square to 74 is 64)

total no. of cases = 74-5+1 = 70 ( +1 since it is an inclusive case)

thus,

P(getting perfect square)= 6/70 = 3/35
