5. The probabilities for Elizabeth and Edward to choose Business as their major are 0.8 and 0.3, respectively.
Find the probability that:
a). Both choose Business as their major.
P = ( both choose Business as their major ) = (0.8) . ( 0.3) = 0.24
b). Neither chooses Business as their major.
P = ( Neither chooses Business as their major ) = (0.2) . ( 0.7) = 0.14
c). Only Elizabeth chooses Business as her major.
I can't find that one I don't know how to do it ? Any formulae ? or Do how can I DO ?
Thanks !

Find the probability that:
a). Both choose Business as their major.
P = ( both choose Business as their major ) = (0.8) . ( 0.3) = 0.24 yes
b). Neither chooses Business as their major.
P = ( Neither chooses Business as their major ) = (0.2) . ( 0.7) = 0.14 yes
c). Only Elizabeth chooses Business as her major.
= ( This means Elizabeth does Business and Edward does NOT do business) = 0.8*0.7 = 0.56
So our guest#1 was totally correct!
Just a guess (0.8). (0.7)
because Edward dosnt choose Business (0.7) and Elizibeth does (0.8)
