Answer: multply
Step-by-step explanation:
Philip and Barbara are 8 meters apart because 5+3=8 so it will make 8 meters
By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
P(A) means "Probability of Event A" The complement is shown by a little mark after the letter such as A' (or sometimes Ac or A): P(A') means "Probability of the complement of Event A" The two probabilities always add to 1.
