If a jar contains 4 red marbles, 6 blue marbles, 3 yellow marbles, and 7 green marbles, what is the probably that a randomly selected marble is red or yellow

35% chance

Step-by-step explanation:

add up total number of marbles 4+6+3+7= 20

add up number of red and yellow marbles 4+3= 7

there is a 7 out of 20 chance that a red or yellow marble is chosen or in other words 35% chance

7:20

Step-by-step explanation:

there's 20 marbles in the jar

4 are red and 3 are yellow

4 + 3 = 7

so 7:20

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4
