Question

Supp_ose that, in a cert_ain sta_ge, only 60% of_ all dri_vers 
re_gula_rly we_ar a seat_be-lt whi_le dri_ving. Supp_ose that 600 drivers 
w_ere random ch_os_en from this stage, fi_nd t_he (approximate) 
proba tha_t more tha_n 375 driv_ers among th_ese 600 dri_vers 
regul_arly wear a se_atbelt w_hile dri_ving? 

According to soluttion at 375 is it shoube + 0.5 or -0.5??
