1. Given p=5−2i and q=−3+7i, write each expression in the form a+bi:
a. p+q−p×q
b. p−q−p÷q 2. a. Solve the equation 2x+1−4=−1.

Bag of 33 tulip bulbs: 14 red, 11 yellow, 8 purple. Select 2 bulbs randomly without replacement. Find probabilities: (a) both red, (b) first red, second yellow, (c) first yellow, second red, (d) one red, one yellow. (a) Probability both bulbs are red: 3314⋅3213
(b) Probability first bulb is red, second is yellow: 3314⋅3211
(c) Probability first bulb is yellow, second is red: 3311⋅3214
(d) Probability one bulb is red, one is yellow: (3314⋅3211)+(3311⋅3214)
