Answer:
30%
number of brown/green m&ms: 75
Step-by-step explanation:
Number of attendees = 14
Number of spies = 4
Number of ways of selecting 10 attendees who are not spies from all the attendees = 14C10 = 1001
Number of ways of selecting 10 attendees from the non-spices attendees = 10C10 = 1
Probability of sharing secret information with 10 non-spies = 1/1001 = 0.000999

Answer:
S=157
Step-by-step explanation:
an= a1+(n-1)d
a2=80+(2-1)(-3)
a2=80-3
a2=77
Sn=(a1+an)*n/2
S2=(80+a2)*2/2
S2=(80+77)*1
S2=157
If you draw the circle and divide into 4 quadrants, you can see that the sine is negative, since the quadrant is situated in the negative part of YY', and that the cosine is positive, since the quadrant is situated in the positive part of XX'.
And
, and negative divided by positive gives a negative answer, which means that the tangent is negative on the quadrant IV.
Hope this helps :)
