    Can someone check these answers that I got and tell me if they are right/ help?

    A mall has three department stores, J C Penney, Macy’s, and Sears. A survey of 1863 people exiting the mall found that 279 made a purchase at J C Penney, 240 made a purchase at Macy’s, 364 made a purchase at Sears, 76 made a purchase at J C Penney and Macy’s, 108 made a purchase at J C Penney and Sears, 95 of them made a purchase at Macy’s and Sears, and 23 of them made a purchase at all three stores.

    a) How many people made a purchase at Macy’s but did not make a purchase at Sears?

    b) How many people made a purchase at exactly one of the three stores?

    Ok so i got
    A) 316
    B) 883

    is this right?
