Can someone please help me understand these 3 probability math problems.

Problem 1:  Option A, 1/8

Problem 2:  Option A, 1/12

Problem 3:  False

Step-by-step explanation:

Problem 1

Step 1:  Find the probability of landing on a red

Red → 1/4

Step 2:  Find the probability of landing on an A

A's → 3/6 → 1/2

Step 3:  Multiply to get the total probability

Red * A's

1/4 * 1/2

1/8

Option A, 1/8

Problem 2

Step 1:  Find the probability of landing on heads

Heads → 1/2

Step 2:  Find the probability of landing on a 5

Die → 1/6

Step 3:  Multiply to get the total probability

Heads * Die

1/2 * 1/6

1/12

Option A, 1/12

Problem 3

Step 1:  Find the probability of choosing a red or white marble

10 + 5 → 15

15 / 35

0.428...

 False

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
