Answer 1

Question:

From the 50 cards numbered from 1 to 50, if a card is drawn at remainder, then the probability of  that number an the card is divisible by 8 is​

Given:

There are 50 cards which are numbered from 1 to 50

To Find:

The probability of getting a number divisible by 8

Solution:

Total number of cards = 50

Numbers divisible by 8 from 1 to 50 = 8 , 16 , 24 , 32 , 40 , 48

So there are 6 numbers divisible by 8

Probability = P( E ) =$\frac{Favorable \:\:Outcomes}{Total\:\:Outcomes}$

P( E ) = $\frac{6}{50}$

$=\frac{3}{25}$

Answer:

The probability of getting a number divisible by 8 is $\frac{3}{25}$
