Answer:
Step-by-step explanation:
-This is a binomial probability problem.
-Given the probability of catching a cold is 0.03, n=6
#The probability of exactly 3 people catching a cold is calculated as:
Hence, the probability of exactly 3 in 6 people catching a cold is 0.0004928
Mindi should have added the 8 and 9 to make the expression 17-9x
This is a case of binomial probability, with n = 29, p = 0.11 and x = 5.
Using the function binompdf on my Texas Instruments calculator, as follows:
binompdf(29,0.11,5) = 0.117 (answer)
Answer:
x=14 and y=7
Step-by-step explanation:
This is a 30-60-90 triangle
So in terms of x it would be 
If across the 60 is 
then y would be 7 which is across the 30 degrees
And x would be 14 because 2(7)=14
