Answer:

Calculating this, we find that approximately 14 rats would be expected to die.

Explanation:

determine the number of rats expected to die, we need to multiply the probability of dying (1 - 0.6 = 0.4) by the total number of rats injected. Probability of dying = 1 - Probability of living = 1 - 0.6 = 0.4 Number of rats expected to die = Probability of dying * Total number of rats injected = 0.4 * 35
