Question

In an experiment, I drew a red card 12 out of 60 times. How many times should I draw red if I draw 100 times?

Answer 1

20

Explanation:

The base number is 60 and the number of correct draws is 12. What you should do is assume this is not an ordinary playing deck. You should also assume that this is a fairly close ratio to what's in the deck. Set up a proportion.

x/100 = 12/60 Multiply by 100

x = 12*100/60 Simplify.

x = 20

Answer 2

Question:-

In an experiment, I drew a red card 12 out of 60 times. How many times should I draw red if I draw 100 times?

Answer:-

Given,

> Number of red cards drawn out of 60 times = 12

Now,

Let the number of red cards drawn out of 100 times be x.

So,

=> x/100 = 12/60

=> 12 × 100/60

=> x = 20
