please solve my question.

Formula Mean for grouped data I = i=1 N Median for grouped data median = L+ ( W ) f med Mode for grouped data mode = L + h fi - fo 2f1 - fo - f2 Variance 1=1 n-1 Skewness skewness = 1=1 (n- 1)s n! Binomial distribution P(x) = p*(1-p)" x x!(n - x)! Geometric p(x) = (1-p)upQuestion 4 (a) In testing a certain kind of truck tire over rugged terrain, it is found that 25% of the trucks fail to complete the test run without a blowout. Of the next 15 trucks tested, find the probability that (i) from 3 to 6 have blowouts (ii) fewer than 4 have blowouts (iii) more than 5 have blowouts (b) A company fabricates special-purpose robots, and records show that the probability is 0.10 that one of its new robots will require repairs during confirmation tests. What is the probability that (0.0478) (i) the eight robot it builds in a month is the first one to require repairs? (ii) the twelve robot it builds in a month does not require any repairs
