Given that events A and B are independent and that P(A) = 0.8 and P(B|A) = 0.4, then P(A and B) = 0.32.

nlexa [21]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

P(A) = 0.8

P(B|A) = 0.4

Since A and B are independent events.

Since P(B|A) is given, we will use the formula for "conditional probability":

So, $P(B|A)=\dfrac{P(A\cap B)}{P(A)}\\\\0.4=\dfrac{P(A\cap B)}{0.8}\\\\0.4\times 0.8=P(A\cap B)}\\\\0.32=P(A\cap B)$

Hence, it is true.

Therefore, Option 'a' is correct.

1) Andrea rents a bike for a day. The rental charges can be determined by

iris [78.8K]

Answer:

$0.5

Step-by-step explanation:

We have been given an equation $R=\$0.5d$ , where R is rental charges and d is number of days Andrea rents the bike. We are asked to find the unit rate.

We know that unit rate represents the ratio between two different quantities. Unit rate represents how many units of one quantity are equal to one unit of another quantity.

Let us divide both sides of given equation by d:

$\frac{R}{d}=\frac{\$0.5d}{r}\\\\\frac{R}{d}=\$0.5$
