Suppose in a math class of 22 students, 14 are boys and 8 are girls. On the final exam, 4 boys and 6 girls made an A grade.
1) If a student is chosen at random from the class, what is the probability of choosing a girl or an A student?
A)10/11
B)2/11
C)3/11
D)6/11
2) If a student is chosen at random from the class, what is the probability of choosing a boy or an A student?
A)10/11
B)2/11
C)3/11
D)6/11
for a girl you have a 8 out of 22 students chance....for an A you have an additional 4 (boys) out of 22 chance
8/22+4/22 = 12/22 = 6/11
for a boy there is a 14 out of 22 chance of being a boy and an andditional 6 (girls) out of 22 for an A
14/22 + 6/22 = 20/22= 10/11
(Not ABSOLUTELY positive of this....but ....mostly ! )
