Question

cards marked with numbers 13, 14 ,15 .... 60 are placed in a box and mixed thoroughly one card is drawn at random from the box . find the probability that number on the card drawn is (1) divisible by 5 ,(2) a perfect sqaure​

Answer 1

Answer:

a) 5/24 b) 1/12

Step-by-step explanation:

since there are 10 prime no.s and 4 perfect squares between 13 and 60

we know

probability = no. of favourable outcomes / no. of outcomes

therefore,

a)

$\frac{10}{48} \\ = \frac{5}{24}$

b)

$\frac{4}{48} \\ = \frac{1}{12}$
