Answer: 0.8588

Step-by-step explanation:

Assume a binomial probability distribution with n = 40 and (symbol looks like a pie sign) = 0.55.  

Compute the following: (Round the value for standard deviation and intermediate calculations to 2 decimal places and your final answer to 4 decimal places.)  

The mean and standard deviation of the random variable.

mean = np = 40*0.55 = 22

std = sqrt(npq) = sqrt(22*0.45) = 3.1464

--------------------------------------------------  

The probability that X is 25 or greater.

P(25<= x <= 40) = 1 - binomcdf(40,0.55,24) = 0.2142

------------------------------------------------------  

The probability that X is between 15 and 25, inclusive.

P(15<= x <=25) = binomcdf(40,0.55,25)-binomcdf(40,0.55,14) = 0.8588

Anne has 24 more cards than devi.  anne finds that 3/5 of devi's cards are equal to 1/2 of her cards.  how many cards does anne
VMariaS [17]
Anne = x
devi = y
x = y + 24
1/2 x = 3/5 y
x = 6/5 y (we devided both by 1/2)
6/5 y = y + 24
6/5 y - y = 24
1/5 y = 24
y = 24 * 5 = 120
x = 120 + 24 = 144
so anne has 144 cards and devi has 120 cards.
