Answer:
<h2><em><u>44</u></em><em><u>.</u></em><em><u>4</u></em></h2>Step-by-step explanation:
<em><u>Let</u></em><em><u>,</u></em>
The number thought by Sushil = x
When halved = x/2
<em><u>We</u></em><em><u> </u></em><em><u>know</u></em><em><u> </u></em><em><u>that</u></em><em><u>, </u></em>
When the number is halved then it becomes 22.2

Answer:
Option A: P(Male or Type B) > P(Male | Type B)
Step-by-step explanation:
Total Female = 85 type A, 12 type B ⇒ 97 Female.
Total Male = 65 type A, 38 type B ⇒ 103 Male
Total type A = 65 + 85 = 150
Total type B = 12 + 38 = 50
total number of people = 97 + 103 = 200
Then the probability would be:
P(Male | Type B) =
=
= 0.368
P(Male or Type B) =
=
=
=
= 0.575
Hence, P(Male or Type B) > P(Male | Type B)
