It’s 4(25+3) because you need to put a line over the 25 and 3 so the 4 can multiply it like so
Answer:
0.12
Step-by-step explanation:
Independent events are when probability of one event happening doesn't affect the probability of the other event happening.
Also,
In probability "AND" means "multiplication" and "OR" means "addition".
The question asks for probability that Nick oversleeps "AND" has pop quiz. So we need to multiply the individual probabilities (since independent, they have no affect on each other).
P(Nick oversleeps) = 0.48
P(pop quiz) = 0.25
Thus,
P(Nick oversleeps AND pop quiz) = 0.48 * 0.25 = 0.12
