Answer:
0.5220
Step-by-step explanation:
Since the probability of contamination is 0.15, the probability of no contamination is 1 - 0.15 = 0.85
The probability that they are all contaminated will be 0.85 * 0.85 0.85 * 0.85 = 0.52200625
This is 0.5220 to four decimal
Answer:
I think that it may be 33
Because, you see 15-9=6
so you do 20-9=11
Then you do 25-9=16
add them all together to get 33 so i think that's the perimeter
I am really not sure if this is correct...i'm kinda bad at stuff like this
