We went over 3 of the questions from yesturdays math sheet
# 3 from the back page
P(E and 20)
cube has 6 sides spinner has 6 sides
6x6 =36
TPO= 36
FO/TPO =5/36 = 0.138 = 13.8 %
#4
P(13 and H)
6 sides on the cube
8 sides on the spinner
6x8=48
TPO=48
FO/TPO= 4/48=1/12=0.08= 8.3%
# 7
P(a number less than 24 and not f )
6 sides on the cube
5 sides on the spinner
6x5=30
FO/TPO= 2/5=O.4= 40%
Then after that we did textbook questions in our notebook about independent probability
TPO on their OWN!
We did question 6 together
P(blue then red)
Blue FO/TPO = 1/10
Red FO/TPO = 3/10 add together TPO is now 20 then add the top parts so the answer is 4/20 =1/5 =20%
P(red then spots )
Red FO/TPO = 3/10
Spots FO/TPO =3/10 add together =3/ 20 = 3/10 = 30%
P( strips then blue)
Strips FO/TPO = 3/10
Blue FO/TPO = 1/10 add together 4/20 = 1/5 =0.2 = 20%
p(blue or red then spotted)
Red and blue FO/TPO 4/10
Spotted FO/TPO 3/10 add together 7/20=0.35 =35%
Here is Number Seven from the textbook
A. Bart FO/TPO = 1/6
Bethany Fo/TPO = 1/6 add together 2/12 =0.16 =16.6%
B. Bart FO/TPO = 1/6
Bethany FO/TPO = 1/6 add together 2/16 = 0.16 16.6%
C.Bart FO/TPO =5/6
bethany Fo/TPO= 3/6 add together 8/12 = 0.66 =66.6%
D. Bart FO/TPO = 3/6
Bethany FO/TPO =3/6 add together 6/12 = 0.5 = 50%
E. Bart FO/TPO = 3/6
Bethany FO/TPO = 3/6 add together 6/12 = 0.5 =50%
For The next scribe i choose simran. Thanks and please leave a comment :)
