Answer:
The number of females is 288.
Step-by-step explanation:
Let the number of females be x.
5:4 = 360:x
We can write the equal ratios as a proportion.
5/4 = 360/x
Cross multiply:
5x = 360 * 4
5x = 1440
x = 288

Step-by-step explanation:
Answer: a) 0.1216
b) 0.8784
Step-by-step explanation:
Let P(watch) = 0.19 ;
And p(don't watch) = 0.81
Find the probability that none of the households are tuned to Found.
P(none) = (0.81)^10 = 0.1216
Find the probability that at least one household is tuned to Found.
P(at least one) = 1-P(none)
1 - 0.1216 = 0.8784
