A tile is chosen at random from a bag containing the following tiles: 7 blue, 3 green, 6 yellow, and 4 purple. Let P be the probability distribution defined on the set {blue, green, yellow, purple}. Write each probability

P of b=7/20

P of g=3/20

P of y=6/20=3/10

P of p=4/20=1/5.

Step-by-step explanation:

there are in total 20 tiles so S=20

there are 7 blue tiles so P=E/S=7/20

there are 3 green tiles so P=E/S=3/20

there are 6 yellow tiles so P=E/S=6/20=3/10.

there are 4 purple tiles so P=E/S=4/20=1/5

d. 9

step-by-step explanation:

54/12 = 4.5

sf = 4.5

so x = 2 · 4.5 = 9

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
