There are 2 seashells and 13 rocks in a bag. You randomly choose two items from the bag. What is the probability that you choose both of the seashells? Write your answer as a fraction in simplest form.

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = Possible outcome of events/total outcome of event

If there are 2 seashells and 13 rocks in a bag, the total number of seashells and rocks will be our total outcome = 2+13 = 15

If a seashell is chosen at random from the bag, the possible outcome will be the total number of seashells = 2

Probability of selecting seashell the first time = 2/15

Probability of selecting seashell the second time = 2/15

The probability that you choose both of the seashells from the bag = 2/15*2/15

= 4/225

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.

answer: i think you should do the math and pay attention in class : )
