Answer:

0.912

Step-by-step explanation:

<em>The complete question is attached.</em>

<em />

"OR" in probability means "ADDITION". So we find the individual probabilities and "ADD" them.

P(Plan A) would be the total people for plan A (add up column of Plan A) divided by total number of people [add up all the numbers].

Looking at the table, we have:

P (Plan A) = 38/68

Now,

P(40-49 Group) can be found by adding up the row of 40-49 age group and dividing by the total. So, we have:

P(40 - 49 Group) = 24/68

Now, adding up both:

38/68 + 24/68 = 62/68 = 0.912

QUESTIONS 1,2,3 PLSSSS (PICTURE ATTACHED) :)
Brums [2.3K]

Answer:

A) 20/6

B)21/16

C)21/10 or 2.1

Step-by-step explanation:

<h2><u><em>EDIT!: someone else who probably has a better understanding than me answered this and I've been doing this all wrong lol please ignore this .w.</em></u></h2>

to find any probability just find the total and then divide that by the number of whatever you're checking for, eg. parkour backgrounds.

A)

7+3+4+6 = 20 total backgrounds

6 parkour backgrounds.

20/6 is your answer.

B)

6 + 10 + 5 = 21 total marbles

10 + 6 = 16 non yellow marbles

21/16 is your answer.

C)

6 + 10 + 5 = 21 total marbles

10 blue marbles

21/10 or 2.1 is your answer.
