Question 770201
Q:
A certain type of seed has a probability of 0.7 of germinating. In a package of 140 seeds, what is the probability that at least 100 will germinate? Please show me formula and calculations
-------------------------------------------------------------------------
A:
X~Binomial(140,0.7)
P(X≥100) = {{{sum((matrix(2,1,140,x))(0.7^x)(0.3^(140-x)), x=100,140)}}} = {{{highlight(0.3955)}}}
