Question

PLZ HELP ME FRNDZZZZZZZ
When Raoul goes to the gym, he does 5 different exercises: bench press, squats, treadmill, leg press, and chin ups. If Raoul always does chin ups before he does bench press, how many different ways can he order his workout?

Answer 1

hmm, ideally there would be 5*4*3*2*1 ways to schedule it

1*1*3*2*1 but the restriction seems to indicate that it should be something like this

Answer 2

a,b,c,d,e ; lets assume d,e have to be in that order

a,b,c,d,e
a,c,b,d,e
b,a,c,d,e
b,c,a,d,e
c,a,b,d,e
c,b,a,d,e

there are 6 ways to run thru it with de at the end, which is what out 1*1*3*2*1 indicates

but we can also shift around the de 3 more times for a total of 4 permuations

Answer 3

6*4 = 24

Answer 4

but then again, it doesnt say that e has to follow d immediatley, only that it has to be after it

Answer 5

i might be thinking into that too much, d right before e seems appropriate

Answer 6

so wht l b da ans???

Answer 7

im sure its the one i posted ....

Answer 8

bt 24 is incrct i dnt knw the crct ans bt i knw that itz incrct

Answer 9

then my second thought was more appropriate ... the information is then telling us that the order of d,e is not restricted to one right after the other ....

Answer 10

i hv gt the ans

Answer 11

we know that for each permuation, there are 6 results

___de
__d_e
_d__e
d___e

4 positions, 3 positions, 2 positions, 1 position each time 6
6*4 + 6*3 + 6*2 + 6

6(10) = 60

Answer 12

yup u r rite
