4. In rolling a fair 6-sided die, let's consider it a \"success\" if we roll a number greater than 4. Suppose we roll the die until we get a \"success.\" (a) (b) (d) Let 'Y be the random variable that counts the number of die rolls until a \"success\" occurs. What type of random variable is X\" Find the probability that \"success\" firat occurs on the fourth die roll. Find the probability that \"success\" first occurs within ten die rolls. Hint: Make use of the cumulative distribution function. Find the probability that \"suecess\" first occurs between the fifth and tenth die rolls (inclusive)
