John has a bag of red and blue marbles. John choses 2 marbles without replacing the first. Let a be the event where the first marble chosen is red. Let b be the event where the second marble chosen is blue. Which statement explains what the equation P (B/A) =0.6 means for those events.

There is 0.6 chance that Joe a blue marble provided that he has already chosen a red marble

Step-by-step explanation:

Given

  ---- first

---- second

Required

Explain what it means

The options are not given. So, I will answer on a general terms.

is the event that B occurs given that A occurs

Using the terms in this question;

there is 0.6 chance that Joe a blue marble provided that he has already chosen a red marble

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

i think it is 18
