Question

What’s the answer for this

Answer 1

Answer:

$0.294$

Step-by-step explanation:

$\text{Here,}\\\text{Total number of students = 25 + 8 + 20 + 32}=85\\\\\text{So, probability that a student is in dance = }\frac{\text{No. of students in dance}}{\text{Total number of students}}=25/85\\\\\therefore\ \text{Required probability = }5/17\approx0.294$

Answer 2

Answer:

33/85=0.38

Step-by-step explanation:

We got totally 85 students

Out of those, we have 25+8 people in dance

Let E represent an event with the probability of a random student being in Dance

Then, P(E)=$\frac{25+8}{85}$

        ∴P(E)=$\frac{33}{85}$=0.38
