P(A and B) expressed in the simplest form is (B) 2/21.
What is probability?
- Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true.
- The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
To express P(A and B) in the simplest form:
- P(A and B) means that you need to multiply the two probabilities together since both A and B need to happen.
- The probability of drawing a black tile on the first draw is 4/15 since there are 15 total tiles and 4 of those are black.
- On the second draw, the bag is already missing a tile, and there are therefore 14 tiles remaining.
- For the second one, the probability is 5/14, since there are 14 total tiles and 5 of them are white.
- Multiplying these two together, we get 4/15 × 5/14 = 20 / 210 = 2/21.
Therefore, P(A and B) expressed in the simplest form is (B) 2/21.
