Find the difference 7 7/8- 3 1/4
grigory [225]
The mixed number have to become a improper fraction and then you have to subtract like this.

so 7 7/8 you have to multiply 7 times 8 and then add it by 7 .
You do the same thing with the other mixed number 3 times 4 plus 1 

So the first one is 63/8 - 13/4 =

first the 4 in the 13/8 have to become 8 . so you do 4 times 2 = 8 and multiply the 13 by 2 = 26 .
so equal 

63/8 - 26/8 = then you have to do 63 - 26 = 37 so is 37/8 and then simplify or divide .

when you divide you suppose to get 4 5/8

What is the probability that the system does not have a type 2defect?b.What is the probability that the system has both type 1 a
Lana71 [14]

Answer:

a.  0.93 b. 0.06 c. 0.05

Step-by-step explanation:

Probability is commonly known as the chance of success of a particular event. The probability of failure of the event can also be estimated.

(a) Probability of not having type 2 defect is: P(A_{2}^{'})  = 1 - P(A_{2}) = 1 - 0.07 = 0.93

(b) Probability of having type 1 and 2 defects is: P(A_{1} n A_{2}) = P(A_{1}) + P(A_{2}) - P(A_{1}U A_{2}) = 0.12 + 0.07 - 0.13 = 0.06

(c) probability pf having both type 1 and type 2 defects but not type 3 defect is:

P(A_{1} + A_{2} + A^{'} _{3}) = P(A_{1} n A_{2}) - P(A_{1} n A_{2} n A_{3}) = 0.06 - 0.01 = 0.05
