Answer:
35/68
Step-by-step explanation:
The first box contains 3 orange balls and 4 black balls.
The second box contains 5 orange balls and 6 black balls
Total number of boxes = 2
Let Pr(F) be the probability that the first box is picked.
Let Pr(S) be the probability that the second ball is picked
Let O be the orange ball selected
Pr(F) = 1/2
Pr(S) = 1/2
Pr(O|S) = n(O) / n(S)
= 5/ 6+5
5/11
Pr(O|F) = n(O) / n(F)
= 3/ 4+3
= 3/7
Pr(S|O) = [Pr( O|S).P(S)] / [Pr( O|S).P(S) + Pr( O|F).P(F)]
= (5/11*1/2) / (5/11*1/2) +(3/7*1/2(
= (5/22) / (5/22 + 3/14)
= (5/22) / (136/308)
= 35/68
Answer:
640 is the Answer
Step-by-step explanation:
If you rotate the triangle so that the 6 is on the bottom, the two sides are both 6.2.
Because the two sides are equal the two angles at the bottom would also be equal. One is given as 61 degrees, so the other bottom angle is also 61 degrees.
The three inside angles of a triangle need to equal 180, so X would equal 180 minus the two bottom angles.
X = 180 - 61 - 61 = 58 degrees.
Itzzzzz 13/15 in simplest form
32 = 2^5 <==== my answer is too short..lol
