Answer 1

15). Given: An un 12 - contains fuchsia marblen 5 - magenta marbler Total = 17 Answer: We have when "2" to find are that botty marbler are magenta , drawn without replacement. → Probability of selecting pet marble id ma gente c tc. Here without replacent of selection Now, we have 4 magenta & 12 fuchsia marsles

→ Probability of selecting and marble is also magata = or on a * P (both marbles are magenta ) - = 0.0735294118 0.074 Option E). was correct

16). Given: An un contains 4 - Blue marbler 8 - Orange marbler = 12 Total Answers 1. We have to find blue & Orange marble be drawn → Probability of selecting the marse that is pst marble out of 12 = c = 4 72c, 12 Here we go through without replacement

→ Probability of selecting and marble that is orange out of 11 = P (Blue and Orange) - * & = 0.242424242 = 0.2424 Option B). was correct
