Question

3.In a survey of 278 women, 195 were found to be working. If a

woman is selected at random, what is the probability that she is not

working?
anyone pls answer the correct answer​

Answer 1

Answer:

83/278

Step-by-step explanation:

total number of women: 278

total number of women working: 195

total number of women not working: 273-195

probability that if a women selected is not working = number of women not working/total no. of women

=83/278

Answer 2

$\huge\sf\underbrace{Question:}$

In a survey of 278 women, 195 were found to be working. If a woman is selected at random, what is the probability that she is not working?

$\sf\Large{\underline{\underline{Answer:-}}}$

We know,

In a survey of 278 women, 195 were found to be working.

So, the number of women not working,

➥ 278 - 195 = 83

∴ 83 women are not working.

ATQ,

It is asked to find the probability that if a woman is selected she is not a working women.

• Number of favourable outcome = 83

• Total outcome = 278

$\begin{gathered}\\\;\sf{:\rightarrow\;\; Probability\;=\;\bf{\dfrac{Number \; of \; favourable \; outcomes}{Total \; outcomes}\:}}\end{gathered}$

$\begin{gathered}\\\;\sf{:\rightarrow\;\; Probability\;=\;\bf{\dfrac{83}{278}\:}}\end{gathered}$

$\Longrightarrow$ $\sf{\cancel\dfrac{83}{278}}$

$\Longrightarrow$ ∴ Probability = 0.299
