Answer:
<u>There are:</u>
- 6 red balls - R
- 5 black balls - B
- Total number = 11 balls
<h3>A. Without replacement</h3>
i. <u>Two blacks </u>
ii. <u>The first is black</u>
or, alternatively
- P(BR or BB) = 5/11*6/10 + 2/11 = 3/11 + 2/11 = 5/11
iii. <u>Both are of same colour</u>
- P(BB or RR) = 2/11 + 6/11*5/10 = 2/11 + 3/11 = 5/11
<h3>B. With replacement</h3>
i. <u>Two blacks </u>
- P(BB) = 5/11*5/11 = 25/121
ii. <u>The first is black</u>
or alternatively
- P(BR or BB) = 5/11*6/11 + 25/121 = 30/121 + 25/121 = 55/121 = 5/11
iii. <u>Both are of same colour</u>
- P(BB or RR) = 5/11*5/11 + 6/11*6/11 = 25/121 + 36/121 = 61/121

amosc??????????????
Step-by-step explanation:
Well, this is basically perimeter and Area. So, if there next door, your going to want to find out 50% of the ice cream shop and candy shop. 40% of it is next to each other . So 40 x 2= 80, there’s the answer . Hope this helps!!!
There's no picture or anything about the shape in the question D: if you're able to explain in the comment I'll help you :D
Answer:
A x = 3
Step-by-step explanation:
A = ½θR²
R = x
x = √(2Α/θ)
θ = (360 - 60)(π/180) = 5π/3 radians
x = √(2(15π/2) / (5π/3))
x = √(15π(3/5π))
x = √9
x = 3
