The probability distribution for a random variable x is given in the table X: -5,-3,-2,0,2,3 Probability: .17,.13,.33,.16,.11,.1
Ivan

Answer:

0.6 probability that -2 \leq x \leq 2

Step-by-step explanation:

The probability distribution is given in the table.

Probability that x is between -2 and 2.

Between -2 and 2, inclusive, we have -2, 0 and 2. So

P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2)

From the table:

P(X = -2) = 0.33, P(X = 0) = 0.16, P(X = 2) = 0.11. So

P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2) = 0.33 + 0.16 + 0.11 = 0.60

0.6 probability that -2 \leq x \leq 2

If two fair dice are rolled, find the probability of a sum of 6 given that the roll
Aliun [14]

Total outcomes of two rolled dice = 6 x 6 = 36

Possibilities for sum of 6 are 3 + 3, 4 + 2, 2 + 4, 5 + 1, 1 + 5. So total possibilities for sum of 6 are five.

<span>Hence the probability for the sum of 6 = 5/36</span>
