Answer #1

We would be looking the first set of questions here as:

Q4) The probability of getting food that is from Restaurant B is computed here as:

= n(Restaurant B) / n(Total)

= 333 / 1113

= 0.2992

Therefore 0.2992 is the required probability here.

Q5) The probability of getting an order that is accurate or is from Restaurant B is computed here as:

= n(Restaurant B or accurate) / n(Total)

= (976 + 55) / 1113

= 0.9263

Therefore 0.9263 is the required probability here.
