Last year 453 new students took the English entrance test. 215 were placed in remedial English. 163 passed remedial English. If a student who took the test is selected randomly. Estimate the probability that:
a) The student who took the test took remedial English.
b) The student who took the test passed remedial English.
c) A student who took remedial English did not pass it.
the answer to a)
215/453= 0.4746the answer to b) is what I question;
163/453= 0.3598 is the number out of all that passed remedial English
So does the answer become (0.4746 + 0.3598) or is the answer (0.4746 x 0.3598)
a) The student who took the test took remedial English.
