Justin writes the letters I-L-L-I-N-O-I-S on cards and then places the cards in a hat. What are the odds of picking an I?
5:3
3:5
2:1
5:7
im thinking its 5:7?
probability of picking i = 3/8
probability of not picking i = 5/8
so
3/8 / 5/8 = 3/5
Nope. I see a total of 8 letters.
Thank you Damon!
there are eight cards in the hat , three of them with an I , five with another letter
3 I's , 5 not .. the odds of an I are 3:5
To determine the odds of picking an "I" from the letters I-L-L-I-N-O-I-S, we need to count the number of "I" cards and divide it by the total number of cards in the hat.
First, let's count the number of "I" cards. In the word "ILLINOIS," there are two "I"s.
Now, let's count the total number of cards. In the word "ILLINOIS," there are a total of 8 letters.
So, the odds of picking an "I" can be expressed as 2:8.
Simplifying this ratio, we divide both numbers by their greatest common divisor, which is 2:8. This simplifies to 1:4.
Therefore, the correct answer is 1:4.
