Question

In survey of 550 children aged 25-46 months it was found that 175 like to eat potato rice if a child is selected at random find the probability that he/she does not like potato rice

Answer 1

Hi,

We know that ,

If the number of favourable outcomes

to E is denoted by n( E ) and number

of all possible outcomes in the

sample space is denoted by n(S),

then

P(E) = n(E) / n(S)

According to the problem given,

n(E) = 550 - 175 = 375

n(E)= 375

n(S) = 550

P(E) = probability of he/she doesn't

like potato rice

P(E) = n(E)/n(S)

= 375/550

= 0.68

I hope this helps you.

:)

Answer 2

Answer:

Step-by-step explanation:

We know that ,

If the number of favourable outcomes

to E is denoted by n( E ) and number

of all possible outcomes in the

sample space is denoted by n(S),

P(E) = n(E) / n(S)

According to the problem given,

n(E) = 550 - 175 = 375

n(E)= 375

n(S) = 550

P(E) = probability of he/she doesn't

like potato rice

P(E) = n(E)/n(S)

= 375/550

= 0.68
