I feel my adults with smart phones are randomly selected 64% use them in meetings or classes if five adults smart phone users are randomly selected find the probability that exactly 3 of them use their smart phones and meetings our classes
Assume that when adults with smartphones are randomly selected, 64% use them in meetings or classes. If 5 adult smartphone users are randomly selected, find the probability that exactly 3 of them use their smartphone in meetings or classes.
2. less than 50?
1. Convert the raw score of 50 to a z score. 2. Draw the normal curve and locate the given z-value or values at the base line of the curve. Then, draw a vertical
line through the given z-value or
values and shade the required region.
3. Use the table and find the area that corresponds to the computed z-score.
4. Examine the shaded region and make an appropriate operation to apply, if needed.
5. Make a concluding statement.

A lottery will be conducted by the Grade 11 students of MNHS to help a fellow student who needs to undergo
an operation. Out of four hundred tickets to be sold, only one ticket will win ₱2,000 and the rest will win nothing.
If you will buy a ticket, calculate for your expected gain.
3. The amount of tea leaves in a can from a production line is normally distributed with μ = 110 grams and σ = 25 grams. A sample of 25 cans is to be selected. What is the probability that the sample mean will be between 100 and 120 grams?
2. At a computer manufacturing company, the actual size of a computer chip is normally distributed with a mean of 1 centimeter and a standard deviation of 0.1 centimeter. A random sample of 12 computer chips is taken. What is the probability that the sample mean will be between 0.99 and 1.01 centimeters?
The scores of all pro golfers for a course are normally distributed with the mean of 70 and a standard deviation of 3. Suppose 36 pro golfers played the course today. Find the probability that the mean score of the 36 pro golfers exceeded 71.
