Question

A number is chosen at random from first 50 natural numbers. Find the probability that it is: an even number and divisible by 7

Answer 1

Answer:

$\bold{\frac{3}{50}}$

Step-by-step explanation:

$The first 50 natural numbers are from 1 to 50. \\ \\ If the number chosen is an even number and also a multiple of 7, then it is a multiple of \ 2 \times 7 = 14 \\ \\ Multiples of 14 among the first 50 natural numbers are 14, 28 and 42. So there are 3 favourable outcomes. \\ \\ As it is taken from the first 50 natural numbers, no. of total outcomes is 50. \\ \\ \therefore\ Probability \ = \bold{\frac{3}{50}}$

Answer 2

s -(first 50 natural number)
n(s)-50
Evant A : even number and divisible by 7
n ( a)-( 14,28 42)
n( a):3
p ( a) :3
