Question

Lucas is choosing a bowling ball to use at the bowling alley. There are 4 black, 5 red, 7 blue, 3 green, and 6 purple bowling balls on the rack. If each choice is
equally likely, what is the theoretical probability that Lucas chooses a red bowling ball?(as a fraction)
Help pls!!!!!!!!

Answer 1

In order to find the answer you have to create a sample space:

S= {b, b, b, b, r, r, r, r, r, b, b, b, b, b, b, b, g, g, g, p, p, p, p, p, p,}

P(b)= 4/25 or 16%

P(r)= 5/25 or 1/5 or 20%

P(b)= 7/25 or 28%

P(g)= 3/25 or 12%

P(p)= 6/25 or 24%

Now the answer is obvious, the theoretical probability that Lucas chooses a red bowling ball is 6/25 or 24%.

Hope this helped, have a good day UwU <3

Answer 2

The theoretical probability that Lucas chooses a red bowling ball is 1/5.

What is the theoretical probability?

Theoretical probability is an approach in probability theory that is used to calculate the probability of an outcome of a specific event.

Lucas is choosing a bowling ball to use at the bowling alley.

There are 4 black, 5 red, 7 blue, 3 green, and 6 purple bowling balls on the rack.

Total number of balls = 4 + 5 + 7 + 3 +6 = 25

If each choice is equally likely, what is the theoretical probability that Lucas chooses a red bowling ball is;

$\rm Probability =\dfrac{Red \ balls}{Total \ number \ of \ balls }\\\\Probability =\dfrac{5}{25}\\\\Probability=\dfrac{1}{5}$

Hence, the theoretical probability that Lucas chooses a red bowling ball is 1/5.
