HELP A pair of fair dice will be rolled. Let the random variable X = the sum of the numbers shown on their faces. The
probability distribution of X is given in the table.
Sum
2 3 4 5 6 7 8 9 10 11 12
Probability 0.028 0.056 0.083 0.1110.139 0.167 0.139 0.111 | 0.083 0.056 0.028
What is the probability that the dice show a sum of at least 6?
P(X

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
