According to the general equation for conditional probability, if P(A, B) =4/7 and P(B) =7/8 - what is P(AIB)?

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

In which

P(A|B) is the probability of event A happening, given that B happened.

is the probability of both A and B happening.

P(B) is the probability of B happening.

We have that:

So

Then

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
