100.
Find the probability of a 1 or a 6 in any given roll and multiply that by the number of rolls.

Explanation:

$Probability = \frac{Favorable Outcomes}{Possible Outcomes}$ $"Probability" = "Favorable Outcomes"/"Possible Outcomes"$

$Favorable Outcomes: 1 or 6 (2 total)$ $"Favorable Outcomes: " 1 or 6 " (2 total)"$

$Possible Outcomes: 1, 2, 3, 4, 5, or 6 (6 total)$ $"Possible Outcomes: " 1,2,3,4,5,or 6 " (6 total)"$

$Probability of a 1 or 6 in any given roll of a die: \frac{2}{6} or \frac{1}{3}$ $"Probability of a 1 or 6 in any given roll of a die: " 2/6 or 1/3$

$\frac{1}{3}$ $1/3$ probability $\times$ $xx$ 300 rolls $=$ $=$ 100 predicted rolls with a 1 or a 6
