You could make an equivalent fraction by multiplying both numbers by 2.
It is not binomial random variable , since the number of red cards is unknown in the deck of cards in the starting of experiment.
As given in the question,
Number of cards are unknown.
Number of red cards are unknown in the starting of experiment.
Number of times process done =10
For binomial random variable number of red cards should be known.
Therefore, it is not binomial random variable , since the number of red cards is unknown in the deck of cards in the starting of experiment.

Answer:
Height of the building ≈ 947.34 ft
Step-by-step explanation:
Jack eyes are 5 ft above the ground .He is standing 500 ft from the base of a building .His line of sight forms angle with the top of the building at 67°. The height of the building can be computed below.
The illustration forms a right angle triangle. The opposite sight of the triangle is the unknown. The height of the building can be found by using the tangential ratio.
adjacent = 400 ft
angle = 67°
tan 67° = opposite/adjacent
tan 67° = a/400
cross multiply
a = 400 tan 67°
a = 400 × 2.35585236582
a = 942.34094633
Adding 5 ft to the total height of the building will be 5 + 942.34094633 = 947.34094633
Height of the building ≈ 947.34 ft
