Lucy rolls 2 fair dice and adds the results from each. Work out the probability of getting a total less than 10.

30/36 OR 5/6

Step-by-step explanation:

First, we have to find the total amount of outcomes that are possible.

We have 2 fair dice and each die has 6 sides so,

6² = 36 (possible outcomes)

Now lets find the possible outcomes that the dice equal more than or equal to 10.

(6+6 = 12), (6+5 = 11), (6+4 = 10)

(5+6 = 11), (5+5 = 10)

(4+6 = 10)

We get 6 possible outcomes. That means we have 30 possible outcomes to get a total of less than 10.

Thus,

30/36 is the probability of getting a total of less than 10.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
