:
There are five students in a group: Amy, Sarah, Jack, David, and Heather. Each one of their names is written on an index card face down. Event C is randomly choosing a name with less than 5 letters. What is the probability of Event C? Express your answer as a fraction.

3/5

Step-by-step explanation:

The probability of an event is the ratio between the number of favourable cases and probable cases.

Probable cases: how many different papers can be drawn: 5, since there are 5 names

Favourable cases: how many draws satisfy event C: 2 because out of the 5 names only three have less than five letters (David and Sarah have exactly 5 so they should not be included).

Probability of event C=2/5

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
