Answer:
1
Step-by-step explanation:
The dot is filled in, meaning the inequality symbol must have an line under it.
Since there's numbers on both sides, you have to simplify so that c is equal to, or greater than 2.
First one;
c-5≥-3
+5 +5
c≥2
It just so happens that this is the correct one, but in the future you may have to go through all.
Hope this helps! If I'm wrong, sorry <3 I haven't done this stuff in awhile.
Answer:
a. 75%
Step-by-step explanation:
Let "p" represent the probability that Jeffrey will eat pizza, and "c" represent the probability that he will drink cola.
We are given ...
P(p) = 0.40
P(p&c) = 0.30
The conditional probability of interest is ...
P(c|p) = P(p&c)/P(p) = 0.30/0.40 = 0.75
The probability Jeffrey will drink cola, given that he eats pizza, is about 0.75.
