Answer:

Step-by-step explanation:
Given: Kristen made 4 out of 5 throws in her first basketball game, 5 out of 8 in her second game and 5 out of 7 free throws in her third game.
To Find: The experimental probability of Kristen marking her first free throw in her fourth game.
Solution:
There are only <u>two</u> possibilities that the first throw will <u>be free</u> or <u>not</u>.
Hence, the <u>total</u> outcomes = 2
Hence, Probability that the throw is free = 
Hence, 1/2 is the experimental probability of Kristen marking her first free throw in her fourth game.
