Abag contains the letters of the word “probability”. a. if a single tile is chosen at random, what is the probability the letter “b” is chosen?

The word probability has 11 letters, there are 2 b's, so, the probability you are asking for is P= 2/11.

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.
