WebMar 1, 2024 · Red-8, Blue-7, Green-6, Total Balls = 21, neither red nor green means only blue color, therefore Probability of blue color = 7/21 = 1/3 Answered by: Dibyendu M. from Kolkata Like Answer: One way of solving this problem is to realise that if the ball oicked up is neither Red or Green, then it must be Blue. WebIn this case, the number of red cards is 3 and the total number of cards is 8, since there are 3 red cards and 5 blue cards. So, P (red card) = 3/8. This can be simplified to 0.375 as a decimal, or 37.5% as a percentage, when rounded to three decimal places. Therefore, the probability of picking a red card is indeed 0.375 or 37.5%.
