Question

Find the probability that when a die is thrown, the number shown is: (i) an even number. (ii) a prime number. (iii) a number less than 5.​

Answer 1

Answer:

i) 2 ii) 2 iii)3/2

Step-by-step explanation:

A={1,2,3,4,5,6}

nA=6

let B be the event were the die thrown shows an even no.

B={2,4,6}

nB=3

probability= nA/nB

=6/3

=2

let C be the event were the die thrown shows a prime no.

C={2,3,5}

nC=3

Probability=nA/nC

=6/3

=3

let D be the event were due thrown shows a number less than 5

D={1,2,3,4}

nD=4

probability=nA/nD

=6/4

=3/2
