Question

A box contains some discs which are numbered
from 5 to 15. If one disc is drawn at random
from the box, then the probability of getting a
multiple of 3 or 4 is ​

Answer 1

Answer:

5/ 11

Step-by-step explanation:

The disc's have been numbered from 5 to 15

And we have to find the probability of getting a disc with multiple of 3 or 4.

Let's see how many multiples of 3 or 4 we have in between 5 and 15,

Multiples of 3 = 6, 9, 12, 15

Multiples of 4 = 8, 12

12 is common in both but there will be only one disc named as 12 so 12 will be taken just once.

•°• => The number of our desired disc's = 5

Total number of disc's = 11

And probability of an event = no. Of favorable outcomes/ total number of outcomes

= 5/ 11
