Question

The probability of a student getting an A in mathematicsis 0.14. The probability a student not getting an A inchemistry is 0.85. The probability that a randomly selectedstudent will get an A in both mathematics and chemistryis 0.03. What is the probability that a student will get an Ain mathematics or chemistry?O 0.2600.7100.7400.29

Answer 1

0.29

Explanation:

Answer 2

0.29

Explanation

Step 1

the probability of an event is the likelihood of that event occuring. Probability is a value between (and including) zero and one

`P=\frac{favorabl\text{e outcomes}}{\text{total outcomes}}`

event1: a student getting an A in mathematics

The probability of a student getting an A in mathematics

is 0.14

`\begin{gathered} P(A)=0.14 \\ \end{gathered}`

and

event b:a student getting an A in chemistry

The probability a student not getting an A in

chemistry is 0.85,it means the probability a student getting an A is 0.15.

`P(B)=0.15`

hence,

the probability that a student will get an A

in mathematics or chemistry is

`P(A\text{ or B)=P(A)+P(B)=0.14+0.15=0.29 }`

I hope this helps you
