Suppose there are 15 jelly beans in a box—4 red, 1 blue, 4 white, and 6 green. A jelly bean is selected at random. What is the probability that the jelly bean is red or blue? (Round your answer to the nearest whole number.) The probability that the jelly bean is red or blue is %.

33% chance

Step-by-step explanation:

Well first we have to create a fraction so we can convert to percent.

It wants us to figure out what the probability will be that a red or blue jelly bean is selected, so we need to add up the blue and red jelly beans.

=

Now we need to convert this to percent. Work:

5 ÷ 15 = 0.33333333333

0.33333333333 ÷ 10 = 0.33

0.33 = = 33%

Therefore there is a 33% chance that the jelly bean picked will be red or blue.

Looking through the solution he made. The second step seem to be erroneous. Clarence did not subtract 15 on the right side. It should be done as follows:

3x + 15 = 33
3x + 15 - 15 = 33 - 15
3x = 18
x = 6

Therefore, from the choices the correct answer is the second option, x should be 6.
