Question

A bag contains cards numbered from 1 to 50 a card is drawn at random find the probability that the card drawn is divisible by 5 t or 3

Answer 1

Answer:13/25

Step-by-step explanation:

Possible outcomes =50

Favourable outcomes = 3,6,9,12.......30,33,36,39,42,45,48

5,10,15.........50.

N(divisible by 5 or 3 )=26

P(divisible by 5or3)=26/50

=13/25

Welcome

Answer 2

Answer:

n(S)=50

Let A be the event of getting a card divisible by 3

A={3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48}

Therefore,n(A)= 16

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

= 50/16

=25/8

Let B be the event of a card divisible by 5

B={5,10,15,20,25,30,35,40,45,50}

n(B)=10

P(B)=50/10

P(B)=5/1
