<u>Answer:</u>
The correct answer option is b) .
<u>Step-by-step explanation:</u>
We are given that the first urn contains 7 white balls and 7 yellow balls and the second urn contains 3 white balls and 6 yellow balls. We are to find the probability that both balls drawn are white.
This means that the first must be white and the second ball must also be white.
P (w, w) = ×
=
Therefore, the probability that both the balls drawn are white is 1/6.
Answer:
∴ ∠BAD = (0.2044) = 11.8°
Step-by-step explanation:
i) AD = 9 cm
ii) DC = 3 cm
iii) ∠BCD = 35°
iv) Since AB is parallel to DC and ∠ABD = 90° then we can conclude that ∠BDC = 90°.
v) = 0.6128 ∴ BD = 3
0.6128 = 1.84 cm
vi) ∴ sin(∠ BAD ) = ⇒ sin(∠ BAD ) =
= 0.2044
∴ ∠BAD = (0.2044) = 11.8°
