Step-by-step explanation:
There would be 0.07923 probability to get 4 aces.
<h3>What is probability ?</h3>
Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Total number of cards in deck = 52
Total number of aces = 4
When 5 cards are chosen randomly,
The probability to get 4 aces
= 1/52+1/51+1/50+1/49+0
Since, at 5th time there will be no ace remains, so probability would be 0.
= 0.01923+0.01960+0.0200+0.0204
=0.07923

Answer:
68 degrees
Step-by-step explanation:
The ladder, the building and the ground together make up a right triangle with angle of elevation to be determined.
The side opposite this angle is 10 ft; the distance of the foot of the ladder from the building is 4 ft. Thus,
tan x = (opp side) / (adj side) = 10/4. Using the inverse tangent function, we find that the angle in question is
arctan (10/4) = 68 degrees
