Answer:
83.78% .
Step-by-step explanation:
The fraction left = (37-6)/ 37
= 31/37
The percent = (31*100) / 37
= 83.78%

Step-by-step explanation:
Number of security doors = 3
Let P denote a successful pass and F denote a failed pass.
Sample space refers to a set of all possible outcomes.
If the first attempt to pass through a door is a failure, then the outcome is F.
If the second attempt to pass through a door is a failure, then the outcome is PF.
If the third attempt to pass through a door is a failure, then the outcome is PPF.
If the fourth attempt to pass through a door is a failure, then the outcome is PPP.
Sample space is
Answer:
a = 38 degree
b = 54 degree
c = 54 degree
Step-by-step explanation:
a = 180 - 142 = 38 ( angle on a straight line is equal to 180)
To determine the value of b, we have to find the other missing angle in the triangle.
the value of the missing angle is 38
Alternate angles are equal. the missing angle is alternate to angle b which has a value of 38
b = 180 - (38 + 88) = 54
c = 54
