Question

A box contains cards numbered 3 to 50. A card is drawn at random from the box. The probability that the drawn card has a number which is a perfect cube, is ​

Answer 1

Answer:

Step-by-step explanation:

S = {3, 4, 5, ..50}

n(S) = 48

Event A: a number is a perfect square

A = {8, 27}

n(A) = 2

P(A) = n(A) / n(S)

       = 2 / 48

       = 1 / 24

Therefore, the probability of getting a number which is a perfect cube is      1 / 24
