Is Urchasko's failure to read the hard copy of the Agreement to Arbitrate enforceable?

Urchasko's failure to read the hard copy of the agreement is no defense. (See Desert Outdoor Advertising v. Superior Court (2011) 196 Cal.App.4th 866, 872 ["[a] cardinal rule of contract law is that a party's failure to read a contract, or to carefully read a contract, before signing it is no defense to the contract's enforcement"]; Madden v. Kaiser Foundation Hospitals (1976) 17 Cal.3d 699, 710 ["one who assents to a contract is bound by its provisions and cannot complain of unfamiliarity with the language of the instrument"].)²

b. The agreement to arbitrate covers this dispute
