Question

In the month of December,2019 find the probability that the days on which the data is multiple of 2.

Answer 1

answer is 15 as december has 31 days and only 15 of thos days are a multiple of 2

Answer 2

P(E)$=\dfrac{15}{31}$

Step-by-step explanation:

We know that,

The total number of days in month of December, 2019 = 31

All possible outcomes are:

1, 2, 3, 4, 5, 6, ......, 31

Total number of possible outcomes = 31

Let E be the event of getting date is multiple of 2.

All favourable outcomes are:

2,  4,  6, ......, 30

Number of favourable outcomes = 15

∴ P(E) $=\dfrac{Number of favourable outcomes}{Total number of possible outcomes}$

$=\dfrac{15}{31}$

Hence,  P(E)$=\dfrac{15}{31}$
