thanks for helping me!
You spin the spinner twice. draw a tree diagram and list sample spaces to show the possible outcomes. From that answer questions 1,2 and 3.
The spinner is 4 equal parts for a, b, c ,d
I know the tree diagram you Have a,b,c,d, and from each of those letters ex. A has four lines so a,b,c,d comes off of the a. do this for each.
sample space:
aa ca
ab cb
ac cc
ad cd
ba da
bb db
bc dc
bd dd
the question I need help on is:
1. P(vowel, b or d)=
I got 1/8 by mult. 1/4*8/16=4/32=1/8
Is this correct?
2. p(a,c)=1/16 which I know is correct
3.P(same letter)=4/16=1/4, which I know is correct
Is the first part correct?
thanks for your help.
Sorry the question was so long
