Solutions
Probability: number of favourable outcomes
__________________________
total number of possible outcomes
In general, the total number of possible outcomes can be determined by multiplying the number of possible outcomes for each event.
P(A|B)=
P(A|B) ⇒<span> P(taking history | taking science) , Therefore A corresponds to taking history, B corresponds to taking science.
</span>
<span>P(A,B) will be the probability that a student is taking both of the subjects.
</span>
<span>P(B) is the probability that a student is taking the subject science (regardless of whether he/she takes history or not)</span>
Now to solve the problem you plug in the given numbers.
</span>
= 0.585<span>37
Rounded to 0.59
Answer = (D) </span>

Now to solve the problem you plug in the given numbers.
0.48 ÷ 0.82
<span>0.48 is the Probability of (A,B) and 0.82 is the Probability of (B)</span>
= 0.585<span>37
Rounded to 0.59
Answer = (D) </span>
