  4. Calculate the probability for each of the following events using R:

    1. A normally distributed variable with mean 31 and standard deviation 2.7 is larger than 34.

    2. A standard normally distributed variable is larger than 2.5.

    3. In a binomial distribution the probability of success is 0.75. If there are 20 trials, what’s the probability of getting 20 successes?
