Question

The probability that, it is Monday and a student is absent is 0.03. Since, there are 5 school days in a week, the probability that a student is absent, given that today is Monday?

• A. 0.15
• B. 0.24
• C. 0.19
• D. 0.21

Answer 1

The correct option is A 0.15

$P\left(\frac{Absent}{Monday}\right)=\frac{P\left(Mondayandabsent\right)}{P\left(Monday\right)}$
=$\frac{0.03}{0.20}=\mathrm{0.15.}$
