Zinaida [17]3 years ago
4 0

Answer:

0.854 (85.4%)

Step-by-step explanation:

Since each bet is independent from others , then for X=gambler’s winnings when she quits

P(X>0) = probability to win in the first bet + probability of losing in the first bet * probability of wining at least one of the 2 additional bets

= 18/38 + (1-18/38) * [18/38*(1-18/38)+(1-18/38)*18/38+18/38*18/38 ] =0.854 (85.4%)

I don’t understand, explain also
Sati [7]

Answer:

32

63

Step-by-step explanation:

m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.

m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.

What is the mode of this data?<br> 1.7 8.9 3 5.9 3.2 4.1 6.6 0.7
ExtremeBDS [4]

Answer:

The value of Mode is 2.43

Step-by-step explanation:

  • To find the mode of the given data first we have to arrange it in a increasing order then find out mean and median of the given data
  • 0.7,1.7,3,3.2,4.1,5.9,6.6,8.9 is in increasing order
  • For finding the median we need to take the average of 4th and 5th terms because we have the no of terms in the sequence is even not odd so we need to take the average the 4th term=3.2 and the 5th term =4.1
  • so average =(3.2+4.1)/2=3.65
  • so the median is equal to 3.65
  • For mean we have to take the average of the data
  • so mean= sum of all data /no of data
  • mean =(0.7+1.7+3+3.2+4.1+5.9+6.6+8.9)/8=4.26
  • so by using the formula we can get mode
  • <em>Mode=3×Median-2×Mean</em>
  • Mode=3×3.65-2×4.26=2.43
  • ∴The value of Mode is given as 2.43
