Find the probability that a randomly selected mobile has a profit greater than R.O ((18x10) +10). b. Any mobile phone which profit is greater than R.O ((18x10) +10) is defined as expensive. Find the probability that a randomly selected mobile has a profit greater than R.O ((1810) +20) given that it is expensive. c. Half of expensive mobile phones have a profit greater than R.O h. Find the value of h.

Create a column of numbers going from 0 to 30. in binomial distrubution with n=30 and p=0.5. Remember that the variance is the expected value of the squared deviations from the mean. In the next column, compute the product of the probability of each outcome and the squared deviation from the mean. Place the sum of the 31 values in the cell next to the cell in which you have computed the variance as a function of the parameters.
