Answer:
calculate P(X=1) + P(X=2) +...+ P(X=12) using the binomial formula or an individual table in excel
calculate the P(X ≥ 12) using the binomial formula or a cumulative table in excel
Step-by-step explanation:
For a binomial distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
n = number of trials = 12 ; x = number of successes
p = probability of success = 0.2% = 0.002
1 - p = 1 - 0.002 = 0.998
Probability that atleast 1 is broken ;
p(1) + p(2) + p(3) +... + p(12) ;
This can be calculated by summing the values obtained using the binomial formula or in excel.
Alternatively, using the binomial formular or excel, the cumulative probability could be obtained as P(x ≥ 1)

The true statement is both the mean and median are greater for Plot A than for Plot B..
<h3>What is the true statement?</h3>
Mean is the average of a data set. Median is the number at the center of a dataset arranged in either ascending or descending order.
Mean for plot A = (3 + 4 + 4 + 5 + 5 + 6 + 6 + 7 + 7 + 10) / 10 = 5.7
Median for plot A = (5 + 6) / 2 = 5.5
Mean for plot B = (3 + 4 + 4 + 5 + 5 + 5 + 6 + 6 + 6 + 7) / 10 = 5.1
Median for plot B = 5

Answer:
30 blocks on the last day and 238 blocks in two weeks
Step-by-step explanation:
4+ 2x
x=0 for the first day
that leaves 13 days so on the last day, she ran 4+2(13)=30 blocks
4+6+8+10+12+14+16+18+20+22+24+26+28+30=238 blocks
