The profits of a mobile company are normally distributed with Mean of R.O (D x 10) and standard deviation of R.O (D).
a. Find the probability that a randomly selected mobile has a profit greater than R.O ((Dx10) +10).
b. Any mobile phone which profit is greater than R.O ((Dx10) +10) is defined as expensive. Find the probability that a randomly selected mobile has a profit greater than R.O ((Dx10) +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.
