So You Think You Know Probability?
P(A or B or both occur) signifies P(AUB) as in set.................... so u have the formula P(AUB) = P(A) + P(B) - P(A n B) same formula applies here too P(A or B or both occur) = P(A) + P(B) - P(A and B) =0.3 + 0.4 - 0.12... -

as geometric sequence help please
QN2) b. now you have value of d and r so find next value in GP after z i.e. In G.P. t4=ar^3 which gives 4th term = 8x (Since a=x and r=2) now In A.P tn = a + (n-1)d for a=d=x tn = x + (n-1)x that gives tn=nx By question tn=8x (next term in A.P which is equal to a term in G.P, all three given... -

as geometric sequence help please
Answer to question 1 When x, y , z are in geometric sequence we get, y/x = z/y To show x^2 , y^2 , z^2 in G.P , 2ndterm(t2)/t1 = t3/t2 i.e. y^2/x^2 = z^2 / Y^2 your answer will be y/x= z/y thats it you got the equation equal to the given one.........Thus they are too in geometric sequence -

its so simple.......... First find the total possible selection of 15 people i.e (20Cr5)^3 = 3.7*10^12 as we have to select five students from each class..... Then find the possible combination of 15 girls, five from each class i.e 10Cr5 * 5Cr5 * 8Cr5 = 14112 now the probability that all 15... -
