Chapter 7.7, Problem 1CYU
Drug Testing A new drug is being tested on laboratory mice. The mice have been given a disease for which the recovery rate is 1/2.
(a) In the first experiment, the drug is given to five of the mice and all five recover. Find the probability that the success of this experiment was due to luck. That is, find the probability that five out of five mice recover in the event that the drug has no effect on the illness.
(b) In a second experiment, the drug is given to 25 mice and 18 recover. Find the probability that 18 or more recover in the event that the drug has no effect on the illness.

7.1 (A/B). A Uniform I-section beam has flanges 150 mm wide by 8 mm thick and a
web 180 mm wide and 8 mm thick. At a certain section there is a shearing force of
120 KN. Draw a diagram to illustrate the distribution of shear stress across the
section as a result of bending. What is the maximum shear stress? [86.7 MN/m².

(b) Let X be a vector space over a field F and A,B are subsets of X such that A is convex set and B is affine set, show that whether AnB is convex set or not, and if f be a function from X into a space Y then f(B) is an affine set or not. /(a) Let M and N be two hyperspaces of a space X write a condition to prove MUN is a hyperspace of X and condition to get that MUN is not hyperspace of X.

A simply supported beam has a span of 6 m and carries a distributed load which varies in a linea manner from 30 kN/m at one support to 90 kN/m at the other support. Locate the point of maximum bendin moment and calculate the value of this maximum. Sketch the S.F. and B.M. diagrams. [U.L.] [3.25 m from l.h. end; 272 KN m 30. 90arrow_forward
