94% of Iowa community college transfers feel that their community college adequately prepared them to handle uppper-division coursework at their transfer university. We randomly survey 14 iowa community college transfers. We are interested in the number that feel that their community college adegqately prepared them to handle upeer division course work at their transfer university. Find the probability that more than half felt that they were prepared.
Find the probability that more than half felt that they were prepared.?
More than half = at least 8, so...
C(14,8)*0.94^8*0.06^6 +
+ C(14,9)*0.94^9*0.06^5 +
+ C(14,10)*0.94^10*0.06^4 +
+ C(14,11)*0.94^11*0.06^3 +
+ C(14,12)*0.94^12*0.06^2 +
+ C(14,13)0.94^13*0.06 +
+ 0.94^14 = get a calculator
Sorry about previous - this is correct.
