Question

A number card is drawn randomly from the set of numbered cards, numbered from 6 to 39. Find the probability that the card may be a prime number or cubed number

Answer 1

Answer: 11/34

Step-by-step explanation:

Solution,

No of sample space n(S)= 34

Prime number ={7,11,13,17,19,23,29,31,37}

n(P)=9

Cube number={9,16}

n(C)=2

We have,

Probability= {n(P)+n(C)}/n(S)

= 9+2/34

=11/34
