180-degree triangle so practically 1 triangle but i am not 100% sure
Answer:
0.047
Step-by-step explanation:
Given that poisson distribution with mean m, for 0.5 square meter =1.5
Then the formula for finding the probability =
P[k] = (e^-m * m^k) k!
Hence we have
P[4] =[ (e^-1.5) * (1.5^4)] ÷ 4 * 3 * 2 * 1
= (0.2231301601 * 5.0625) ÷ 24
=( 1.12944375) ÷24
= 0.04706
≈ 0.047
Hence, the final answer is 0.047
