If a and b are independent events with p(a) = 0.05 and p(b) = 0.65, then the conditional probability p(a |
alukav5142 [94]
Two events are said to be independent when the occurence of one event does not in any way affects the occurence of the other event.

For independent events, the probablilty of event A happening given that event B has happened is given by the probability of event A happening.

i.e. P(a | b) = P(a).

Therefore, given that p(a) = 0.05 and P(b) = 0.65, then p(a | b) = p(a) = 0.05.

melamori03 [73]

Answer:

-8

Step-by-step explanation:

Solving for w given the equation, -3w +5 = 2:

-3w +5 = 2 \\ -3w +5 -5 = 2 -5 \\ -3w = -3 \\ \frac{-3w}{-3} = \frac{-3}{-3} \\ w = 1

Solving for w -9 when w = 1

In timara math class there are, 12 boys and 15 girls which of the following in the ratio to boys and girls in timaras math class
tiny-mole [99]

Answer:

4:5

Step-by-step explanation:

If there are 12 boys and 15 girls, the ratio of boys to girls will be 12:15.

However, this can be simplified by dividing each number by 3. This can be done since both 12 and 15 are divisible by 3.

12:15

= 4:5

So, the ratio of boys to girls in Timara's class is 4:5
