Final answer:
The probability that Jeremiah will randomly select a yellow T-shirt is 1/2, as he has 8 yellow T-shirts out of a total of 16 T-shirts.
Step-by-step explanation:
The subject of this question is probability, a branch of Mathematics. To find the probability that Jeremiah will randomly select a yellow T-shirt, we look at the number of yellow T-shirts over the total number of T-shirts. Jeremiah has 8 yellow T-shirts out of a total of 16 T-shirts. Therefore, the probability (P) that a T-shirt is yellow when selected at random is: P(yellow T-shirt) = Number of yellow T-shirts / Total number of T-shirts
= 8 / 16
= 1/2 or 0.5 when reduced, which could also be considered as a '50% chance'.
