Question

1. If a number is chosen at random from the set {1, 2, 3…, 100}, then the probability that the chosen number is a perfect cube is

Answer 1

Answer:

1 ÷25

Step-by-step explanation:

$p(e) = number \: of \: favourable \: outcome \: \div total \: number \: of \: outcomes$

Total number of outcomes- 100

No of favourable outcomes - 4

$p(perfect \: cube) = 4 \div 100$

$p(e) = 1 \div 25$
