Question

What is the probability of getting a number less than 11?

Answer 1

10/11 is the probability of getting number less than 11

.....

Answer 2

The probability of getting a number less than 11 $=\dfrac{11}{12}$

Step-by-step explanation:

When two dice are thrown:

Total number of possible outcomes = $6^{2}$ =36

The number greater than 11 are:

(5, 6), (6, 5) and (6, 6)

Total number of favourable outcomes = 36 - 3 = 33

∴ P(getting a number less than 11) $=\dfrac{Number of favourable outcomes}{Al possible outcomes}$

$=\dfrac{33}{36}$

$=\dfrac{11}{12}$

The probability of getting a number less than 11 $=\dfrac{11}{12}$

Hence, the probability of getting a number less than 11 $=\dfrac{11}{12}$
