Help, please. It is a probability question.

P=0.1227

P=12.27%

Step-by-step explanation:

Pita has 12 coins in her bag. 3 of those coins are £1 coins and 9 are £0.50.

She takes 3 coins from her bag at random. We want to calculate the probability that she takes exactly £2.50.

To take £2.50, there is only one way to combine three coins:

Two of £1 and one of £0.50

The £1 coins can be extracted from the 3 available

The £0.50 coin can be extracted from the 9 available.

The combination of both events can be calculated as:

The sample space is the total combination of possible events:

And the probability is:

P=0.1227

P=12.27%

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
