30 students could of been taking both courses and 60 with no course
Answer:
36
Step-by-step explanation:
3/4y=6-1/3c
3/4y+1/3c=6
multiplied 6 into equation to get 2c
9/2y+2c=36
so 2c+9/2y=36
Found and simplified x divided by y I think:|
Let success be that a plant dies in the winter and failure be that a plant survives the winter, then
p = 0.05, q = 1 - 0.05 = 0.95
a.) P(1 or more will not survive the winter) = 1 - P(all will survive the winter) = 1 - P(0) = 1 - 10C0 (0.05)^0 (0.95)^10 = 1 - 1(1)(0.5987) = 0.4013
b.) P(all will survive) = P(none will die) = P(0) = 0.5987
Answer:
rational because it's a decimal
