solve for m
0.2m=3.5

Answers

Answer:

m = 17.5

Step-by-step explanation:

Given 0.2m=3.5, we want to solve for m.  This involves isolating m on the left side.  To accomplish this, divide both sides by 0.2, obtaining:

m = 3.5/0.2, or m = 17.5

A bag contains 2 black balls, 4 yellow balls and 4 white balls. Event A is defined as drawing a white ball on the first draw and event B is defined as drawing a black ball on the second draw. If two balls are drawn from the bag, one after the other and not replaced, what is P(B|A) expressed in simplest form? A. B. C. D.

Answers

Answer: [tex]P(B|A)=\dfrac{4}{9}[/tex]

Step-by-step explanation:

Given: A bag contains 2 black balls, 4 yellow balls and 4 white balls.

Event A is defined as drawing a white ball on the first draw.

Event B is defined as drawing a black ball on the second draw.

P(B|A) is expressed as the conditional probability of occurring B given that A.

i.e. it is the probability of happening B where A is already happended.

If a white ball is drawn at first, then the number of black ball(4) remains unchanged but the total number of balls (10) will become 9.

[tex]Probability=\dfrac{Number\ of \ favorable \ outcomes}{Total\ outcomes}[/tex]

Then, [tex]P(B|A)=\dfrac{4}{9}[/tex]
