Question

a dice is thrown one time find the probability of getting the composite number on its upper face?

Answer 1

Answer:1/3.

Step-by-step explanation:

Total possibilities s={1,2,3,4,5,6}

n(s)=6

Composite numbers a={4,6}

n(a)=2

P(a)=2/6

     =1/3.

Answer 2

Total number of outcomes are = 6

i) Let E be the event to get a composite number

number of favourable outcomes of the experiment = 2 ( 4,6 )

number favourable outcomes
p(E) = ------------------------------------------
Total number of outcomes

p(E) = 2/6

p(E) = 1/3
