What is the probability of rolling a sum of 7 when rolling 2 dice?

0.296

0.296

Step-by-step explanation:

Binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1-p).

P = ₁₂C₂ (0.167) ² (1-0.167) ¹²⁻²

P = 66 (0.167) ² (0.833) ¹⁰

P = 0.296
