ent is chosen at random, what is the probability of choosing a girl or an A student?
1 answer:
Answer:
0.634 is the required probability.
Step-by-step explanation:
We are given the following in the question:
Total number of students = 30
Number of girls = 17
Number of boys = 13
Number of A students = 5
Number of A students that are girl = 3
We have to find the probability choosing a girl or an A student.

Answer:
Add em both and set em equal to 180
20+(6x-2)=180
18+6x=180
6x=162
X=27
That is in simplest form if you are talking about in decimals the answer would be 0.02739
Answer:
the right answer is option D. 0.5b
I just want you know that there is another easier method
Answer:
x=16
so B
Step-by-step explanation:
Answer:
Because 6X will cancel out, leaving you with no x. And 3 does not equal -5.
Step-by-step explanation:
6X + 3 = 6X -5
-6X -6X
3= -5 (not true)
