Do the usual standardizing. just replace µ with 7/3 *σ^2 -

there also have to arrangements when 3 Gs are together then. -

Im not sure. but i think u can take probability at 63 to be 0.75 since it is upper quartile. u do know the mean. P(63-mean/ S.D) =.75 try -

smartangel. Apparently u need a tutor. Too many doubts :O :P -

Remember the fi thing i said before, use that formula P( k-mean/standard devation <Z< 128-mean/s.d) = .7465 -

Explain this please (7*6*5*(6!/3!)). -

Since there's replacement so ill not consider P or C. just poweres. since 12 pic cards are there and i have to pic 3. 12^3. dividing by 3! is to cut down the number of arrangements OF THIS SELECTION. same goes for the rest. 8! is an overall arrangement ( 8 cards) -

probability of sth to happen = x when it is happening more than 1nce and being independent (no replacement/removal), then to happen next time, probability will be same so if they tell u to find that that this happens twice. Probability will be x *x = x^2. if thrice, then x^3
