I really need help with this Experimental Probabilities.

126

Step-by-step explanation:

From the statement , we have been given given

blue jays : black crows : red robins : cardinal

That is :

59 : 68 : 12 : 1

Total ratio = 59 + 68 + 12 + 1 = 140

Therefore : the number of blue jays if 300 visit is :

ratio of blue jay / total ratio x 300

That is

59/140 x 300

= 126. 4285714

≈ 126

Hi!

Assuming the 9in is the radius, we would multiply it by 2, or add it to itself. We then get 18 in.

Hope this helps!
