5+9=14 in numerical expression
Given that 3/5 know fortran
1/6 know cobol
1/10 know both fotran and cobol
the fraction of programmers who knows at least one of the two programs will be:
3/5+1/6+1/10
=13/15
the fraction of programmers who don't know either of the two will be:
1-13/15
=2/15
thus the answer is 2/15
Answer:
the expected total amount of time in minutes is 88.4
Step-by-step explanation:
