A bag contains 6 pennies, 5 nickels, 3 dimes, 4 quarters, 2 half-dollars, & 1 silver dollar.

If draw a single coin from the bag:

Question 1: What is the probability of drawing a silver-colored coin?

A coin worth more than 20 cents?

A coin with ridged edges?

Probability of silver colored coin

P(silver colored coin) = (21 - 6) / 21 = 15 /21 or 5/7

Probability of a coin worth more than 20 cents

P( coin is > 20 cents) = ( 4 + 2+ 1)/21 = 7/21 = 1 /3

Probability of ridged edge coin:

P(ridged edged) = (3 + 4 + 2+ 1)/21 = 10 /21

Points = 28.5 + 0.31wages - 0.0002wages Squared

Question 2: How many more points will a team earn if they increase wages from £80 to £100 million
