You multiply .2 by every number in the parentheses. So .2 times 2.50, which is 0.5, .2 times 4.95, which is .99 and .2 times by 6, which is 1.2. then you add .5, .99 and 1.2 to get 2.69.

Step-by-step explanation:
Formula : Probability = 
Given , Sam has 4 cards numbered 2,3,5, and 7.
His friend has 4 cards numbered 1,2,6 and 7.
If they both draw one card and put that on table , then the possible combinations of cards would be (2,1) , (2,2), .... (7,6), (7,7).
i.e. Number of possible outcomes would be (S) 4 x 4 = 16
Favorable outcomes that they will choose same number (F) = (2,2) , (7,7)
Now , the probability that they will both choose the same number would be :

Hence, the required probability = 
Answer:
The length of segment PQ is 
Step-by-step explanation:
we know that
Applying the Intersecting Tangent-Secant Theorem

we have



substitute





therefore
The length of segment PQ is 
4 miles= 21120 ft
5 miles= 8800 yd
