## Omniscience 3 years ago Jane has three red shirts and two yellow shirts. On each of the three days, Monday, Tuesday, and Wednesday, she selects one shirt at random to wear. Jane wears each shirt that she selects only once. (a) What is the probability that Jane wears a shirt of the same colour on all three days?

Do i use the probability tree diagram? if yes, how do i draw it? i havent done in a very long time..

2. Omniscience

done these*

Jane has three shirts and two yellow shirts. ???? three red ?

4. Omniscience

5. Omniscience

@lgbasallote: very easy one for you :P

6. lgbasallote

sorry cant understand problem. i am bad english

7. Omniscience

lol, illiterate :P i need help tho -_- i dont know how to draw the tree diagram

that is not write tho sami

10. Omniscience

right* lol

11. sami-21

i think both probabilities should be multiplied . try that :P

12. Omniscience

the answer is 3/4 * 2/4 * 1/3 but the problem is that i dont know how to draw the probability tree diagram to see it

the two yellow shirts are not enough for three days.. so we are finding the probability that she wear a red shirt each day on monday the probability that she wear a red shirt is 3/5 (since we have 3 red shirts out of a total of 5 shirts) on tuesday we have only 4 shirts left.. 2 of them are red so the probability that she wears a red shirt on tuesday is 2/4 on wednesday 3 shirts are left.. only one of the is red so the probability thet she wears a red shirt on wednesday is 1/3 now multiply them the answer is (3/5)*(2/4)*(1/3)

i got it thanks! but it is possible to draw a probability tree diagram for it?

15. Omniscience

is it*

16. hoblos

well.. may be :P im not that good in drawing tree diagrams !

17. Omniscience

ok ty anyway
