lola rolls a die 3 times . what is the probability that she gets a 4 on the last one of the 3 rolls ?
the die has 6 sides and it was rolle 3 times , then 6 * 6 * 6 = 216 the number of ways to get 4 is 1 then 1 / 216 the probability would be 1 - 1 / 216 = 215 / 216 answer a
subtract(const_1, multiply(multiply(divide(const_1, const_6), divide(const_1, const_6)), divide(add(4, const_1), const_6)))
