A forecast is to be made of the results of five cricket matches, each of which can be a win or a draw or a loss for Indian team. Let `p=` number of forecasts with exactly 1 error `q=` number of forecasts with exactly 3 error `r=` number of forecasts with all five error Then the correct statement(s) is/are a. `2q=5r` b. `8p=q` c. `8p=r` d. `2(p+r)> q`

A forecast for Indian team is to be made of the results of five cricket matches, each of which can be win,draw or loss for indian team. (i) Total no. of possible forecast

A forecast forr Indian team is to be made of the results of five cricket matches, each of which can be win,draw or loss for indian team. (i) Total no. of possible forcast

the results of 11 chess matches (as win , lose or draw ) are to be forecast . Out of all posible forecasts, the number of ways in which 8 correct and 3 incorrect results can be forecast is

Two teams are to play a series of five matches between them. A match ends in a win, loss, or draw for a team. A number of people forecast the result of each match and no two people make the same forecast for the series of matches. The smallest group of people in which one person forecasts correctly for all the matches will contain n people, where n is a. 81 b. 243 c. 486 d. none of these

The mean of is same as the mean of Then which of the following is correct? p=q=r (b) q=r=s q=r (d) p=r+s

Given that P(3,1),Q(6. 5), and R(x , y) are three points such that the angle P R Q is a right angle and the area of R Q P is 7, find the number of such points Rdot

Let p be the statement "x is an irrational number", q be the statement "y is a transcendental number " and r be the statement "x is a rational number iff y is a transcendental number". Statement - 1 : r is equivalent to either q or p. Statement -2 : r is equivalent to ~(p harr ~q)

Consider the equation p = 5-2q - 3 If p = |r| + 5 , then number of possible ordered pair (r,q) is, are

Statement 1: If p ,q ,ltr , the number of different selections of p+q things taking r at a time, where p thingks are identical and q other things are identical, is p+q-r+1. Statement 2: If p ,q ,>r , the number of different selections of p+q things taking r at a time, where p thingks are identical and q other things are identical, is r-1.
