Answer:
a) 0.108
b) 1.00
c) 0.170
d) 0.0109
e) 0.0121
f) 0.999
Step-by-step explanation:
Success: p = 0.15
Failure: q = 1 - p = 0.85
a) q²p = 0.85² × 0.15
= 0.108375 = 0.108 (3 sf)
b) 1 - P(all hits)
= 1 - p⁷ = 1 - 0.15⁷
= 0.9999982914= 1.00 (3 sf)
c) q³p + q⁴p = 0.1704196875
= 0.170 (3 sf)
d) 7C4×p⁴×q³ = 35 × 0.15⁴ × 0.85³
= 0.01088152734 = 0.0109 (3 sf)
e) P(4,5,6 or 7)
= 7C4×p⁴×q³ + 7C5×p⁵×q² +
7C6×p⁶×q + 7C7×p⁷×q⁰
= 0.01210317188 = 0.0121 (3 sf)
f) 1 - P(more than 4)
= 1-(0.01210317188-0.01088152734)
= 1 - 0.001221644531
= 0.9987783555 = 0.999 (3 sf)
Answer:
0.07776, 0.3456,0.08704
Step-by-step explanation:
Given that a new surgical procedure is said to be successful 60% of the time
Let X be the no of successes
Then X has only two outcomes and each trial is independent of the other
Hence X is binomial with p = prob of success in a single trial = 0.60
n = Number of operations performed = 5
Prob that
a) all five operations are successful =

(b) exactly three are successful
=
(c) less than two are successful

Answer:wheres the photo at doe
Step-by-step explanation:
its the first option.
tiles of X and tiles of 1 are different
3 tiles of "X" = 3X
3 tiles of " 1 " = 3
option 3 does not mean 3X, it just means 3X + 3
