The probability would be 0.5
Answer:
r = 9/sin Ф or r = 9 csc Ф
Step-by-step explanation:
The polar form is represented as:
x = r cos Ф and
y = r sin Ф
We are given:
y = 9
Putting value in y = r sin Ф
9 = r sin Ф
=> r = 9/sin Ф
1/sin Ф = csc Ф
or, r = 9 csc Ф
When you say either, you add both A and B
0.3+0.4=0.7
Your answer is 0.70 which means 70%
So firstly, multiply both sides by 4 (the reciprocal of 1/4): 
Next, subtract both sides by 2 and your answer will be:
