Answer:
P(Male = 2) = 63.9%
Step-by-step explanation:
40000C2 / 50000C2
[(40000 * 39999) / (1*2)] / [(50000 * 49999 *) / (1*2)]
3,199,920,000 / 4,999,900,000
0.6399996799935999
P(Male = 2) = 63.9%
X=2
Explanation:
You need to find the midpoint of the segment
-2+6=4
4/2=2
It’s the second option counting from top to bottom
No of red marbles = 5
Total number of marbles =14
By using probability formula,
P(E)= Number of favorable outcome /
Total number of outcomes
P(E)= 5/14

Answer:
<u>56.5 ft</u>
Step-by-step explanation:
See the attached figure which represents the explanation of the problem.
We need to find the length of the tree to which is the length of AD
From the graph ∠BAC = 90° and ∠ABD = 76°, AB = 18 ft
At ΔABD:
∠BAD = ∠BAC - ∠DAC = 90° - 4° = 86°
∠ADB = 180° - ( ∠BAD + ∠ABD) = 180 - (86+76) = 180 - 162 = 18°
Apply the sine rule at ΔABD
∴
∴ 18/sin 18 = AD/sin 76
∴ AD = 18 * (sin 76)/(sin 18) ≈ 56.5 (to the nearest tenth of a foot)
So, The length of the tree = 56.5 ft.
<u>The answer is 56.5 ft</u>
