Find the probability of drawing a 6 and then a 6 (without replacement) from a standard deck of carNs.

A deck of cards has 52 total cards and four 6’s

Picking a 6 first would be 4/52 = 1/13

Without replacing there are 51 cards left and three 6’s

Picking a 6 would be 3/51 = 1/17

Probability of doing both is:

1/13 x 1/17 = 1/221

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

pi x^2

step-by-step explanation:

pi times x squared
