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
The place value is the hundreths
1. 672/12 = 56
2. 1440/16 = 90
3. 784/7 = 112
Answer:
5.25inches
Step-by-step explanation:
difference in height = 68.5-63.25 =5.25
Answer:
2k + 80
Step-by-step explanation:
Combine like terms.
3k + 8 - k + 72 =
= 3k - k + 8 + 72
= 2k + 80
