Answer:
5n+5
Step-by-step explanation:
5(n+3)-10
5n+15-10
5n+5
3 1/2 divided by 2 1/4 = 1.55555556
1.55555556 Rounded is 1.55
0.25 and 1/4 are the same number.
If each one is the probability of some event,
then both events are equally likely.
It's difficult to draw a tree diagram with this software.
Try to do it yourself & you will find the followings:
If A is selected (P(A) =1/2) we can get ether red (p(A & red)=4/7
so P(A∩red)= 1/2 x 4/7 = 4/14
Also we can get P(blue) = 3/7 & P(A∩blue) = 1/2 x 3/7 = 3/14
Same reasoning for B & you will get P(B∩read) 1/2 x 3/4 = 3/8
Also we can get P(B∩blue) = 1/2 x 1/4 = 1/8
Probability of blues is either 3/14 or 1/8
P(blue) = 3/8 +1/8 =19/56 = 0.339
