(a) What is the probability that two randomly selected tulip bulbs are both red? (b) What is the probability that the first bulb selected is red and the second yellow? (d) What is the probability that one bulb is red and the other yellow? (a) The probability that both bulbs are red is 0.135 (Round to three decimal places as needed.)Explanation / Answer
p(red bulb) = n(red bulb) / n(total bulb) = 11/ 29
p( yellow bulb) = n(yellow bulb) / n( total bulb) = 9/29
a)
p( both bulb are red ) = p(first bulb red) * p(second bulb red)
= 11/ 29 * 10 / 28 ( since first red bulb is drawn 10 bulb left for second draw with 28 total bulbs)
= 0.135
b)
p( first bulb is red AND second bulb is yellow) = 11/ 29 * 9 / 28
= 0.122
