Question

The blood types of 200 people are collected at the doctor's office. The table shows the breakdown of patients per blood type. If a person from this group is selected at random, what is the probability that this person has type O blood? Mason has 213 songs on his ipod. He's categorized them in the following manner: 20 from sound tracks, 8 spiritual, 31 jazz, 16 Latin American, 27 R&B;, 47 rock, and 64 pop. If Mason puts his ipod on shuffle, what is the probability that the next song played will be a pop song?

Explanation / Answer

11. Suppose that there are m things in total. And t of them are of type I. Then if we randomly pick something randomly from from m things the probability that it is of type I is t/m.

There are 50+65+70+15 = 200 people in total. Out of these 70 have blood group 'O'. So if we select a person at random the probability that the person is of O group is 70/200 = 0.35

12. Mason has 20+8+31+16+27+47+64 = 213 songs. Out of these 64 are pop. Now if randomly pick a song the probability that is is pop is 64/213 = 0.3005.
