We know that there is a 0.60 probability that a random student at UMSL has watched Game of Gnomes. We calaculate the probability that 3 of 4 students watched Game of Gnomes.

$p=0.6\\q=1-0.6=0.4\\$

Therefore, we get:

$P=C_3^4\cdot 0.6^3 \cdot 0.4^1\\\\P=4\cdot 0.6^3 \cdot 0.4\\\\P=0.3456$

Therefore, we conclude that the probability is P=0.3456.

HELP! Find area of trapezoid

grandymaker [24]

The area of a trapezoid is found by averaging the bases and multiplying the height. to average the bases, you take 22ft + 14ft to get 36ft and then divide it by 2 since there are 2 numbers to average to get 18ft. Then you just multiply that by 8ft to get your area of 144ft^2 (square feet).
