Hello. I need help with step by step instructions to answer these questions so I can do similar ones.

1. In the binomial formula p(x)=(4Cx)(0.2)^x(0.8)^(4-x), the probability of success is 80%. True or False. How do you calculate to know?

2. Hot Ovens Company sells kitchen stoves. Company is currently forecasting customer demand to be normally distributed with mean of 100 stoves for the year and standard deviation of 25 units. What is the probability that the Company will sell at least 50 kitchen stoves this year?

3. The distance travelled by transport trucks per day is normally distributed with a mean of 540 km and standard deviation of 80 km. What is the probability a truck travels between 600 km and 640 km in a day?

4. X is a normally distributed random variable with a mean of 35 and a standard deviation of 10. The probability that X is less than 9 is: How do you find X?

5. If X is normally distributed with a mean of 10 and standard deviation of 2.5, then P(X>12)=0.8.True or False. How do you calculate to know?
