Describe the likelihood of the next elk caught being unmarked.
tangare [24]

Using it's concept, it is found that there is a 0.96 = 96% probability of the next elk caught being unmarked.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, 5625 - 225 = 5500 elks out of a total of 5625 are unmarked, hence the probability is given by:

p = 5500/5625 = 0.96.

we can replace h with 3h and see what happens

A=1/2b(3h)
A=3/2bh
A=3(1/2bh)
